ABSTRACT

Phanera yunnanensis (Franchet) Wunderlin, comb, nov, is proposed. The "Yunnan bauhinia"
is grown as an ornamental in southern peninsular Florida and has been recognized in previous
accounts to be naturalized in Mami-Dade County, Florida.

KEY WORDS: Bauhinia, Phanera, Fabaceae.

Phanera Racldi (Fabaceae: Cercideae: Caesalpinioideae) consists of 90-100 species native to
Asia and the Malesian region of the Old World (Wunderlin 2010). The genus is readily distinguished
from other genera of the Cercideae by consisting of lianas (rarely shrubs) with tendrils (rarely
without) and 3 (rarely 2) fertile stamens.

The "Yunnan bauhinia," Bauhinia yunnanensis Franchet, native to southern China, Myanmar,
and Thailand, is a glabrous, woody climber to 5 meters and blooms from late spring to early fall.
Occasionally cultivated in tropical and warm temperate regions of both the Old and New World, it is
easily grown from seed which is readily available from a variety of commercial sources. Naturally
dispersed seeds remain viable for several years. Grown in southern peninsular Florida for several
decades, it is naturalized in Miami-Dade County as reported in Wunderlin (1998), Wunderlin and
Hansen (2003, 2011), and USDA, NRCS (2011). Although long regarded as a Bauhinia, it is best
placed in the genus Phanera and the combination in that genus is made here.

The name Bauhinia [Phanera] saigonensis Pierre ex Gagnepain of Cambodia, Laos,
Thailand, and Vietnam is frequently misapplied to Phanera yunnanensis. The latter is distinguished
by its spatulate petals that are pinkish with dark red veins and the stamens and style subequaling the
petals in contrast to the linear-oblong, white petals and the stamens and style much longer than than
the petals in B. saigonensis.
